SECU'lRING AND RELEASING APPLIANCE.

Application filed November 23, 1914.

To all w/wm it may concern:

Be it known that I, FRED DE Mass, a citizen of the United States, residing at Traverse City, in the county of Grand Traverse and State of Michigan, have invented certain new and useful Improvements in Securing and Releasing Appliances; and I do hereby declare the following to be a full. clear, and exact description of the in-- vention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a device designed to supply means for connecting a draft rope or chain with a pulling means, and also means for quickly releasing said rope or chain.

An object of my invention is to supply a cheap, eflicient and reliable device to accomplish the results set forth above.

In the drawing herewith which is made a part of this application, Figure 1 is a side elevation with the lever in normal position. Fig. 2 is a side elevation with the lever thrown back to release the chain from the hook, and Fig. 8 is a plan view of my device with the lever fully extended to the rear.

In the detail description of my invention the body portion consists of two parallel side plates 1 and 2. Fixedly mounted between the said side plates is the hook bearing member 3, secured between the side plates by the bolt 4. Rotatably mounted on the point of the hook 5 of the member 3 is the ring 6 depending from the point of said hook within the curve thereof in such a manner that it can be swung forwardly but not rearwardly thus forming a lock against the casual removal of a ring or link to which said hook may be attached.

At the end of the body portion opposite to that bearing the hook 5 is pivotally mounted a lever 7 secured to the body portion by the bolt 8, the end of said lever which is pivotally mounted between the two members 1 and 2 of the body portion is curved upwardly and backwardly upon itself to form a fiat hook 9. The slot 10 formed between the body portion 9 of the hook and the point 11 thereof is positioned above the axial or horizontal plane of the bolt 8 when the lever handle is in its normal position so that the line of draft on said hook will register with the line of draft on the front hook 5 and be Specification of Letters Patent.

held above the center of gravity until such time as it is desired to release the object connected to the hook 9, thus lending a self locking action to the hook. Through the means of the bolt 4 and a rivet 12 the laterally extending member 13 is secured to the plate 2 of the body portion to provide a means for safely and conveniently operating the device.

In operating my invention the hook 5 is connected with the pulling means which may be a double tree attached to a team, or a rope attached to a power operated Windlass, and the hook on the lever 7 is connected with a draft rope or chain. When it is desired to stop the pull instantly the operator slightly thrusts the handle of the lever upward or until the pull on the hook 9 is moved to a point below the axis of the bolt 8 or below the center of gravity, when the tension on the hook will cause it to fall farther backward and release the draft rope or chain. It is especially adapted to use in connection with the means for handling logs, when it is necessary to stop the movement of a log at a particular point, when the moving of it too far is liable to cause an accident. To stop a team or the motive power of a hoister is not always practical. With my device the stop can be made just as described. It is also adapted for use with a team working on a hay sling. The rope may be dropped without stopping the team resulting in a great saving of time during a days work as ordinarily the team must be stopped and then backed up to release the rope from an ordinary hook attached to the double tree.

Having thus fully described my invention, it is believed that its construction, advantages and manner of using are clearly understood.

V hat I desire to secure by Letters Patent is:

A device of the class described comprising a pair of side plates forming a body portion, a hook bearing member secured between said plates, one end of the member terminating a distance within the ends of the plates and the opposite end thereof projecting beyond the ends of the plates and forming a hook, a pivoted link carried by said hook, a lever pivoted between the ends of the side plates projecting beyond the hook bearing member, one end of said lever havmg a handle portion and the opposite end a In testimonv whereof I have signed my hook, said hook being so arranged with rename to this specification in the presence of spect to the lever as to rest above the center two subscribing witnesses.
